      Solution:

      (i) 9: 16

      We know that

      Sub-duplicate ratio of 9: 16 = √9: √16 = 3: 4

      (ii) ¼: 1/9

      We know that

      Sub-duplicate ratio of ¼: 1/9 = √1/4: √1/9

      So we get

      = ½: 1/3

      = 3: 2

      (iii) 9a2: 49b2

      We know that

      Sub-duplicate ratio of 9a2: 49b2 = √9a2: √49b2 = 3a: 7b
